XWD型臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥(wo)式靜電(dian)(dian)(dian)(dian)除塵(chen)器(qi)是(shi)以靜電(dian)(dian)(dian)(dian)凈化(hua)法(fa)來收(shou)捕(bu)廢氣(qi)中(zhong)的(de)(de)粉塵(chen)，它(ta)的(de)(de)凈化(hua)工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉淀(dian)兩(liang)個系統來完成的(de)(de)，當含(han)塵(chen)氣(qi)體進(jin)(jin)人(ren)(ren)氣(qi)刺叭時，含(han)塵(chen)氣(qi)體受到氣(qi)流(liu)(liu)(liu)分布板以及折流(liu)(liu)(liu)板的(de)(de)調整后，使(shi)氣(qi)流(liu)(liu)(liu)能較(jiao)均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大的(de)(de)作(zuo)用下，氣(qi)流(liu)(liu)(liu)速度(du)迅(xun)速降低，其中(zhong)有(you)些(xie)較(jiao)重的(de)(de)塵(chen)粒(li)(li)便(bian)失(shi)去速度(du)而沉降下來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)氣(qi)體由于(yu)電(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高壓(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)體中(zhong)存在(zai)(zai)大量(liang)的(de)(de)電(dian)(dian)(dian)(dian)子和離子，這(zhe)些(xie)電(dian)(dian)(dian)(dian)子和離子與(yu)進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)結(jie)合起來，使(shi)塵(chen)粒(li)(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒(li)(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用下趨(qu)向本(ben)設(she)備陽極(ji)(正極(ji)、本(ben)設(she)備采用負(fu)高壓(ya)制)和陰(yin)極(ji)(負(fu)極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子分別(bie)沉積在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通過設(she)備陰(yin)陽極(ji)振打系統的(de)(de)振打，使(shi)沉積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)粉塵(chen)振落，進(jin)(jin)人(ren)(ren)集灰斗 通過排(pai)灰裝置(zhi)放出(chu)，回收(shou)有(you)物料，被)凈化(hua)的(de)(de)氣(qi)體排(pai)入大氣(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)工(gong)作(zuo)原理是利用(yong)高壓(ya)電(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)作(zuo)用(yong)下與氣(qi)(qi)流分離。負極(ji)由(you)不同(tong)(tong)斷面形狀(zhuang)的(de)(de)金屬(shu)導線(xian)制成(cheng)，叫(jiao)(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)(tong)幾何形狀(zhuang)的(de)(de)金屬(shu)板(ban)制成(cheng)，叫(jiao)(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)性能受粉塵(chen)(chen)性質(zhi)、設備構造和煙氣(qi)(qi)流速等三個(ge)因素的(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的(de)(de)指(zhi)標，它對除塵(chen)(chen)效率(lv)有直接(jie)的(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)粒難以保持在(zai)(zai)(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)阻過(guo)高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易放出，在(zai)(zai)(zai)塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)壓(ya)梯度(du)會(hui)產生(sheng)局部擊穿和放電(dian)(dian)(dian)現象。這些情況都會(hui)造成(cheng)除塵(chen)(chen)效率(lv)下降。

電(dian)(dian)除(chu)塵(chen)器的(de)基本原理(li)是利用電(dian)(dian)力(li)捕集煙氣中的(de)粉(fen)塵(chen)，主要包括(kuo)以(yi)下四個相互有關(guan)的(de)物理(li)過程: (1) 氣體的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)的(de)捕集。
